Australia eSIM
Optus
eSIM travel data plan for Australia — 5 GB of full-speed 3G/4G/5G data per day on the Optus network, valid for each day purchased. After the daily allowance, browsing continues uninterrupted at up to 384 Kbps.
Install it any time within 180 days of purchase. Installing does not start your plan: the 1 Day validity begins when the eSIM first connects to a network in Australia. We recommend installing over Wi-Fi before you travel.
With a Daily Plan, you have the flexibility to purchase exactly as many days as your trip requires. With this plan, each day, you'll enjoy 5 GB of high-speed data to keep you moving.
If you happen to use your daily 5 GB , don't worry—you’ll stay connected at a reduced speed (up to 384 Kbps) for the rest of the day. It’s still plenty for staying in touch via messaging, checking maps, or light browsing until your high-speed limit resets the following morning. It’s reliable, seamless coverage tailored to your schedule. Read the full Fair Use Policy
